As if it's name does not make it obvious enough, the Asus Zenfone 4 Selfie is all about selfies, being one of the first few smartphones to rock the popular (as of 2017) dual-camera technology up front 
. This comes in the form of a high-resolution 20-megapixel f/2.0-aperture camera with Asus's signature PixelMaster technology coupled with an 8-megapixel 120-degree-angle 6P-lens sub-camera, the latter enabling wider shots and depth-of-field analysis . Additionally, it features instant camera switching and a dedicated front-firing Softlight LED flash .

Selfies and groupfies are not its only strengths, though, since the Zenfone 4 Selfie also touts a high-ranking 16-megapixel rear-facing camera bedecked with phase-detection autofocus and a real-tone LED flash . That being said, this camera-centric smartphone sticks to a Full HD (1920 x 1080) maximum video recording resolution 
, instead of reaching for a premium 4K (3840 x 2160) capability, although its electronic image stabilization is a nifty accompaniment.
Among its cons is the Zenfone 4 Selfie's 5.5-inch display settling for a discouraging HD-720p resolution that cannot even hold a candle to its sophisticated cameras. It also only comes with 3000mAh of battery power , which is relatively modest, considering that several other premium camera phones go way over the 4000mAh threshold.

The Zenfone 4 Selfie only comes with 64GB of on-board memory , which joins its aforementioned underwhelming specs, considering that several other high-end 2017 models pack up to 128GB storage memories. It is not that big of a setback, however, since it supports a whopping up to 2TB of top-up memory -- the highest microSD storage allowance offered by a mobile device as of August 2017.
Looking into its hardware pros and cons, this selfie-focused Zenfone 4 variant may pack 4GB's worth of RAM and an Adreno 505 graphics processor , but the 1.4GHz maximum clock speed of its Snapdragon 430 eight-core engine does not promise much . In comparison, many other high-end contenders use octa-core chips that clock in at 2GHz or higher.

Although its selection of pros and cons includes a humdrum display, the Zenfone 4 Selfie nevertheless calls out to high-end shoppers who place very high value on a phone's imaging capabilities.
